Orientation adjusting stereo audio output system and method for electrical devices


Arrangements described herein relate to systems and methods for adjusting the audio output from an electrical device based on the orientation of the device to provide proper stereo audio output for more than one orientation of the device. The audio output system includes at least two speakers. The device includes an orientation sensor, which can be accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. The audio output system can be operatively connected to the orientation sensor. Based on orientation data collected by the orientation sensor, output from the audio output system can be adjusted to provide audio output from opposing left and right regions of the device. Such adjustments can be implemented by the orientation sensor itself or by a switching device (such as a processor, digital logic gate or switching transistor) operatively positioned between the orientation sensor and the audio output system.

FIELD

Embodiments relate in general to electrical devices and, more particularly, to electrical devices that provide stereo audio output.

BACKGROUND

Some portable electrical devices, such as smart phones and tablet computers, are configured to provide stereo audio output. Stereo audio output is achieved by providing two speakers in opposite regions of the device. For instance, these two speakers are usually positioned on the left and right sides of the device or along the left and right ends of one edge of the device.

Some application software programs being executed on such electrical devices may generate video output that is best suited to a specific device orientation. For example, some games are designed for a portrait aspect ratio, while some others are best viewed in a landscape mode. However, tilting the device at a 90 degree angle can change the orientation of the speakers provided on the device. Thus, instead of providing audio from the left and the right, as intended, the speakers (and the sound emitted therefrom) may now be from the top and bottom of the device, destroying the left/right separation of audio channels. As a result, a user\'s enjoyment of the audio aspects of the device may be diminished.

Moreover, some portable electrical devices, like tablet computers and cell phones, contain orientation sensors and allow the visual output of applications and media to be presented properly regardless of the device\'s orientation. For example, a video can be displayed on the portable electrical device. The device can be placed into one of four possible orientations. A user can watch video on the device when the device is in any of four orientations because the orientation sensor ensures that the video is presented in the proper orientation. However, with a conventional two-speaker device, proper stereo output is provided in only one of these orientations.

Thus, there is a need for a system and method that can minimize such concerns.

SUMMARY

In one respect, embodiments relate to an electrical device having an audio output system and an orientation sensor. The electrical device can be a cellular telephone, a smart phone, a personal digital assistant, a tablet computer, a laptop computer, a digital reader, a portable electrical device, a portable computing device, an entertainment device, a global positioning system device, a digital audio player, an e-book reader, a camera or a game console.

The audio output system includes two or more speakers. In one embodiment, one speaker can be located within a first region of the electrical device, and a second speaker can be located within a second region of the electrical device. The first region can be opposite the second region. In one embodiment, the audio output system can include three speakers.

The orientation sensor is configured to collect data regarding the orientation of the electrical device. The data regarding the orientation of the electrical device is used to adjust the output from the audio output system. In this way, stereo audio output can be provided for a plurality of orientations of the electrical device. In one embodiment, stereo audio output can be provided from opposing left and right regions of the electrical device for at least two different orientations of the electrical device.

The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, a pressure sensor to detect the points at which the electrical device is being supported or combinations thereof. In one embodiment, the orientation sensor can be directly connected to the audio output system. In such case, the orientation sensor can be, for example, a mercury switch or a ball-bearing based position sensor. In another embodiment, the orientation sensor can be indirectly connected to the audio output system. In such case, a switching device can be operatively positioned between the orientation sensor and the audio output system. As an example, the switching device can be a processor. The processor can be configured to: determine the orientation of the electrical device based on orientation data collected by the orientation sensor, and adjust output from the audio output system based on the determined orientation. As another example, the switching device can be a switching transistor. As yet another example, the switching device can be a digital logic gate.

In another respect, embodiments are directed to an orientation adjusting stereo output method for an electrical device. The device has an audio output system including at least two speakers.

According to the method, data regarding the orientation of the electrical device is collected. The output from the audio output system is adjusted based on the data collected regarding the orientation of the electrical device. As a result, stereo audio output can be provided for a plurality of orientations of the electrical device. The method can further include determining whether the orientation of the electrical device has changed. If the orientation of the electrical device has changed, the audio output from the audio output system can be adjusted such that stereo audio output is provided from the electrical device to accommodate the new orientation.

In one embodiment, the adjusting can be performed by an orientation sensor. The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, a pressure sensor to detect the points at which the electrical device is being supported, or combinations thereof. In another embodiment, the adjusting can be performed by a switching device operatively positioned between the orientation sensor and the audio output system. The switching device can be a processor, a switching transistor or a digital logic gate.

In one embodiment, the audio output system can have three speakers. In such case, the adjusting can include selecting at least two of the three speakers based on the determined orientation of the electrical device such that the selected speakers provide stereo audio output from the electrical device. Audio data can be output from the selected speakers.

In still another respect, embodiments are directed to an electrical device. The electrical device can be a cellular telephone, a smart phone, a personal digital assistant, a tablet computer, a laptop computer, a digital reader, a portable electrical device, a portable computing device, an entertainment device, a global positioning system device, a digital audio player, an e-book reader, a camera or a game console.

The electrical device includes an audio output system, which has at least three speakers: a first speaker, a second speaker and a third speaker. The device also includes an orientation sensor that is configured to collect data regarding the orientation of the electrical device. In one embodiment, the orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. Alternatively or in addition, the orientation sensor can be a pressure sensor to detect the points at which the electrical device is being supported.

Further, the device includes a processor that is operatively connected to the audio output system as well as to the orientation sensor. The processor is configured to (a) determine the orientation of the electrical device based on orientation data collected by the orientation sensor; (b) select at least two of the speakers based on the determined orientation of the electrical device; and (c) output audio data to the selected speakers. Thus, stereo audio output can be provided regardless of the orientation of the electrical device. The stereo audio output can be provided from opposing left and right regions of the electrical device.

The processor can be further configured to determine whether the orientation of the electrical device has changed based on orientation data collected by the orientation sensor. If the orientation of the electrical device has changed, the audio output from the audio output system can be adjusted such that stereo audio output is provided from the electrical device to accommodate the new orientation.

In one embodiment, the first speaker can be located within a first region of the electrical device. The second speaker being located within a second region of the electrical device. The first region can be opposite the second region. The third speaker can be located in the first region or in the second region of the device.

In yet another respect, embodiments are directed to an orientation adjusting stereo output method for an electrical device. The device has a processor, at least three speakers, and an orientation sensor. The processor is operatively connected to the at least three speakers as well as to the orientation sensor. The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. Alternatively or in addition, the orientation sensor can be a pressure sensor to detect the points at which the electrical device is being supported.

According to the method, the orientation of the electrical device is determined based on orientation data collected by the orientation sensor. At least two of the three speakers are selected based on the determined orientation of the electrical device. The selected speakers can be on opposing left and right regions of the electrical device. Such selection can include selecting speakers that are located on opposing right and left regions of the electrical device. Audio data is output to the selected speakers. Thus, stereo audio output is provided regardless of the orientation of the device.

The method can also include determining whether the orientation of the electrical device has changed based on orientation data collected by the orientation sensor. If the orientation of the electrical device has changed, at least two of the three speakers can be selected based on the determined orientation of the electrical device to accommodate the new orientation. Thus, stereo audio output can be provided regardless of the orientation of the device.

Embodiments described herein can be implemented into any suitable electrical device, including any of those listed above. The electrical device 10 can include any suitable operating system.

Some of the various possible elements of the exemplary electrical device 10 shown in FIG. 1 will now be described. It will be understood that it is not necessary for an electrical device 10 to have all of the elements shown in FIG. 1 or described herein. The electrical device 10 can include a processor 12. The processor 12 may be implemented with one or more general-purpose and/or special-purpose processors. Examples of suitable processors 12 include microprocessors, microcontrollers, DSP processors, and other circuitry that can execute software. It should be noted that there may be instances in which the electrical device 10 does not include a processor 12 or the processor 12 is otherwise not involved in the adjusting of the audio output of the electrical device 10, as described in detail below. “Processor” means any component or group of components that are configured to execute any of the processes described herein.

The electrical device 10 can collect information from which the orientation of the electrical device 10 can be determined. To that end, the electrical device 10 can include one or more orientation sensors 18. “Orientation sensor” means one or more devices, components and/or structures that collect data as to the orientation of an object. “Orientation” means the position of an object relative to a frame of reference. The orientation sensor 18 can be any suitable type of orientation detecting and/or determining hardware and/or software. For instance, the orientation sensor 18 can be an accelerometer, gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or other suitable sensor, or combinations thereof. Further, the orientation sensor 18 may be a pressure sensor to detect the points at which the electrical device is being supported, such as the points at which the device is engaged by a user\'s hand and/or a surface upon which the electrical device 10 is resting.

The orientation sensor 18 can be operatively connected to the processor 12. As will be described below, the processor 12 can use information received from the orientation sensor 18 to adjust audio output of the electrical device 10 to maintain stereo audio output regardless of the orientation of the electrical device 10. However, it should be noted that, embodiments are not limited to such an arrangement. Indeed, alternative arrangements can include electrical devices 10 in which the switching of speaker outputs can be implemented in any suitable manner, including, for example, in an analog configuration or other forms that do not use computing elements.

The electrical device 10 can include an input system 20 for receiving input from a user. Any suitable input system 20 can be used, including, for example, a keypad, display, touch screen, button, joystick, mouse, microphone or combinations thereof. The electrical device 10 can include an output system 22 for presenting information to the user. The audio output system 22 can include an audio interface that can include one or more microphones, earphones and/or speakers. Additional features of the audio output system 22 will be described below. The electrical device 10 may also have additional output systems 21 for presenting information to the user. For instance, the additional output systems 21 may present visual information to the user and, in such case, can include a display. It should be noted that one or more of the items noted above may serve dual purposes such that the item is part of the input system 20 as well as the audio output system 22 and/or additional output systems 21.

The electrical device 10 may optionally include a component interface 24. Additional elements can be operatively connected to the component interface 24, including, for example, a universal serial bus (USB) interface or an audio-video capture system. The electrical device 10 may include a power supply 26. As is shown in FIG. 1, the processor 12, the memory 14, the transceiver 16, the orientation sensor 18, the input system 20, the audio output system 22, the other output system 21, the component interface 24 and/or the power supply 26 can be operatively connected in any suitable manner.

The electrical device 10 can have a housing 30, which can at least partially enclose one or more of the functional components of the electrical device 10, including the various components shown in FIG. 1. The housing 30 can be made out of any suitable material. The housing 30 can define at least a portion of the overall shape of the electrical device 10. The housing 30 can have any suitable shape, including a rectangular shape. While the housing 30/electrical device 10 is shown in FIGS. 2-5 as being substantially rectangular, it will be understood that embodiments are not limited to such a configuration. Indeed, it will be appreciated that embodiments described herein can be applied to housings and/or electrical devices with any suitable geometry, including, for example, those that are substantially circular, oval, parallelogram, trapezoidal, polygonal, triangular, or irregular just to name a few possibilities.

The audio output system 22 can comprise a plurality of speakers. Any suitable number of speakers can be provided. In one embodiment, the audio output system 22 can include at least three speakers, as is shown in FIGS. 2-5. There can be a first speaker 31, a second speaker 32 and a third speaker 33. A “speaker” is defined as one or more devices or components that produce sound in response to an audio signal input. Examples of speakers include, for example, electroacoustic transducers, sound chips, and sound cards. Each speaker 31, 32, 33 can have one or more audio output channels (not shown) operatively connected thereto. “Audio output channel” is defined as any suitable device, component or structure for carrying audio signals.

Data collected by the one or more orientation sensors 18 can be used to adjust the audio output of the electrical device 10 as appropriate to maintain stereo audio output. Such adjusting can be achieved directly or indirectly. Each of these possibilities will be considered in turn below.

An example of an electrical device 10 having a direct switching system is shown in FIG. 6. In such case, the orientation sensor 18 can be configured so that the orientation of the electrical device 10 can cause contacts provided by the orientation sensors 18 to be made and/or broken. Thus, when the electrical device 10 is held in one position, certain contacts between the orientation sensors 18 and the audio output system 22 can be made and/or broken. When the electrical device 10 is held in another position, different combinations of contacts between the orientation sensors 18 and the audio output system 22 can be made and/or broken. In one embodiment, the orientation sensors 18 could be mercury switches. Alternatively or in addition, the orientation sensors 18 could include ball bearing-based position sensors. Again, these specific structures are provided merely as examples, and embodiments are not limited to these particular examples.
